Underground Rapper of the Week is a new feature designed to raise awareness of rappers from all over the world who, if that world were a perfect place, would be more famous than they are. It will be updated every Tuesday before the sun goes down. Feel free to email suggestions of slept-on rappers from your city or wherever to: ezra.stead@gmail.com

Few underground rappers are more innovative and influential than California’s Gift of Gab, best known as the emcee half of the great Hip-Hop duo Blackalicious, complemented by DJ Chief Xcel. Gab is well-known by heads everywhere for his amazing verbal dexterity and immediately recognizable style, as well as his uncommon intelligence and careful enunciation on the mic. “Alphabet Aerobics,” from Blackalicious’ 1999 A2G EP, is a perfect example of his showy, technical side, as he flips a continuous stream of lyrics that only speeds up and gets more complex as he cycles through the entire alphabet, devoting approximately two bars to each letter.

However, Gab is not just a gimmicky, smarter-than-thou rapper’s rapper. What really sets him apart is his insightful, positive and elevating lyrical content, as heard on songs like “Shallow Days,” from Blackalicious’ 1999 debut full-length, Nia, where he laments the superficiality of consciousness in Hip-Hop culture: “The word ‘peace’ is just an expression / Used to say ‘bye’ when it’s time to jet and / Them red, black and green medallions / Was all just part of a trend, I guess / Hardly ever see them around brothers’ necks no more.” Tracks like this and the storytelling anthem, “Deception,” on which he chants the mantra, “Don’t let money change you,” show Gab to be relentlessly positive and forward-thinking, though he is quick to remind listeners he is not judging anyone for how they might be forced to live. As he says on “My Pen and Pad,” from Blackalicious’ 2005 album, The Craft, he is “never an anti-gangster – the ghetto is still in the mind.”

As great as A2G, Nia and The Craft are, Blackalicious’ indisputable masterpiece is 2002′s Blazing Arrow, a truly epic collection that feels like a culmination of everything the Xcel and Gab had done up to that point. It also features stellar work from a variety of other artists affiliated with Blackalicious and the Quannum Projects, including Nikki Giovanni, Gil Scott-Heron, DJ Shadow, Lyrics Born, Saul Williams, Zack de la Rocha of Rage Against the Machine, and Chali 2na of Jurassic 5, among others. My introduction to the wonders of Blackalicious began with the apocalyptic “Sky Is Falling,” on which Gab paints a dark picture of a world in which “juveniles is losing trials, catching a bid of murder one / And mothers is drinking and drugging, hoeing, searching for their sons.” Blazing Arrow is full of gems like that song, as is Blackalicious’ entire catalogue.
